VEHICLE SPEED CONTROL
I was turning out of my neighborhood and as I accelerated to merge with traffic my car started jerking. My dashboard “D” symbol only started flashing on and off and then my transmission service required light came on, (just had it done 8/25 and it is 11/25) and the BSW service required light came on as well. As I continued down the street everytime I pressed on the gas pedal the car kept jerking backwards and forward.

Driving home with no other cars around the forward collision warning goes off for no reason losing power and slowing down on it's own. This has been an ongoing situation since the car was new, I've made numerous attempts to have my local dealership look into this situation and all they tell me is to take video when it happens.

I have 40,000 miles on my vehicle, only owner and drive 28 miles to and from work a day. The entire Infotainment center is not usuable, I called the dealership I purchased it from and they said the warranty is 36,000 miles. How on a brand new car do you get 36,000 for a system that controls everything inside your car.

I had a recall on this vehicle for the CVT software update which i got fixed by mitsubishi at the dealership but now its doing the same thing and seems worse, everytime I push on the gas it does not excelerate and usually gets stuck at 30-45MPH no matter how much i press on the gas, and the rpms get stuck at 3-4 thousand rpms which causes a safety threat when we are driving. I did some research and found out that this a well known issue with mitsubishi and its outlander sports vehicles I’m not sure what to do from here.

ELECTRICAL SYSTEM
I was driving approximately 35MPH on a 4-lane road with no vehicles in front of me. The car came to a hard stop. The stop was so hard that my purse flew from the passenger seat to the floor. I was wearing my seat belt which tightened up but my body still moved forward causing me neck pain. I did notice briefly that a flashing yellow light was on the dashboard. There were no objects in front of me. The driver of the car behind me had to slam on their brakes and almost hit my car. My car stayed still for about 15 seconds and then the automatic brake was released.
